Back driving a CIM

[matthewdenny]

We are thinking about the possibility of a drive motor being only occasionally used, and freely spun by the gear box when not used for acceleration/pushing.

We also have a swerve design where to rotate the wheel 90 degrees it would have to back drive a cim a rotation or two.

We would like to know how much torque it takes to do this. Also is the torque required the same regardless of the speed of rotation?

In both cases the coma would be hooked up speed controllers, but not receiving voltage from them.
